Wedge Edges Length

The Edge Length of a Wedge calculator computes the total length of the edges of a wedge shaped object based on its dimensions.

INSTRUCTIONS: Choose units and enter the following:

• (H) Height 
• (W) Width
• (D) Depth

Wedge Edges Length (L): The calculator returns the length in meters.  However, this can be automatically converted to compatible units (e.g., inches, feet) via the pull-down menu.

The Math / Science

A wedge is geometrically a three dimensional triangle with triangular ends.  The formula for the sum of the edges of a wedge is:

`L =  2*D + 2*H + 2* sqrt(D^2+H^2) + 3*W`

where

• L = Total Edge Length of a Wedge 
• W = Width
• D = Depth
• H = Height

A wedge is a three-dimensional geometric shape that has a right - triangular cross-section with a 90^o corner and typically tapers from a thick end to a thin edge. It can be thought of as a prism with a triangular base, where one face is slanted, forming an inclined plane. It has five sides.

Properties of a Wedge Shape:

• Base: Typically a rectangle or a parallelogram.
• Sides: At least one slanted face, usually a triangle.
• Edges: The meeting points of the faces create sharp edges, often leading to a thin end.
• Angles: The wedge often has an acute angle at one end and a broader face at the other.

Examples of Wedges in Real Life:

• Tools: Axe heads, chisels, doorstops.
• Natural Forms: Some rock formations and ice wedges.
• Engineering: Airplane wings and hydrofoils have wedge-like cross-sections for aerodynamics
